Abstract: The study in this thesis is based on the statistical analysis of the stellar population properties of galaxies, combining di↵erent kinds of data. In particular we use Integral Field Spectroscopy (IFS) provided by CALIFA data and images in optical and UV range provided by SDSS and GALEX, respectively. The main goal is to obtain the cosmic evolution of the star formation and mass assembly history of galaxies using integrated and spatially resolved information of galaxies in the near Universe. The objects in this study are those for which CALIFA+GALEX+SDSS data are available. This is a sub-sample of 366 galaxies which is unbiased with respect to the CALIFA mother sample, including from E to late type spirals and with M? from 109 to 8⇥1011 M!. The CALIFA mother sample is not a purely volume-limited sample, but can be “volume-corrected”. As the sub-sample is representative of the CALIFA mother sample, our results can be used to estimate the star formation rate density (⇢SFR), the specific SFR (sSFR) and the stellar mass density (⇢Mass) up to z > 2, and the contribution of central (<0.5 HLR) and outermost regions (1 < R < 2 HLR) in nearby galaxies to these fundamental observables in astrophysical cosmology.
